Automation of Quantum Dot Measurement Analysis via Explainable Machine Learning

January 13, 2025
Author(s)
Daniel Schug, Tyler Kovach, Michael Wolfe, Jared Benson, Sanghyeok Park, J. P. Dodson, Joelle Corrigan, Mark Eriksson, Justyna Zwolak
The rapid development of quantum dot (QD) devices for quantum computing has necessitated more efficient and automated methods for device characterization and tuning. Many of the measurements acquired during the tuning process come in the form of images

Polynomial-Time Classical Simulation of Noisy IQP Circuits after Constant Depth

January 12, 2025
Author(s)
Joel Rajakumar, James Watson, Yi-Kai Liu
Sampling from the output distributions of quantum computations comprising only commuting gates, known as instantaneous quantum polynomial (IQP) computations, is believed to be intractable for classical computers, and hence this task has become a leading

Expanded quasi-static models to predict the performance of robotic skins on soft cylinders

January 11, 2025
Author(s)
Jennifer Case, Gabrielle Branin, Ellen Yang, Stephanie Woodman, Rebecca Kramer-Bottiglio, James Gibert
Robotic skins are planar substrates with embedded sensors and actuators that are designed to wrap around soft, passive objects to enable multiple functionalities, such as locomotion and manipulation. We previously introduced a control model that relied on

2024 NIST Summary of U.S. Legal Metrology Activities

January 10, 2025
Author(s)
Juana Williams, John McGuire, Loren Minnich, Gloria Lee, Jan Konijnenburg, Isabel Baucom, Katrice Lippa
The NIST Office of Weights and Measures (OWM) presents its second issue of the 2024 NIST Annual Summary of U.S. Legal Metrology Activities report. This report includes a summary of changes made to NIST Handbook 44 (2024) Specifications, Tolerances and

Checking the Net Contents of Packaged Goods

January 10, 2025
Author(s)
John McGuire, David Sefcik, Loren Minnich, Isabel Baucom, Katrice Lippa
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of packaging, distribution, and sale of

Commutability Assessment of New Standard Reference Materials (SRMs) for Determining Serum Total 25-Hydroxyvitamin D using Ligand Binding and Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS) Assays

January 10, 2025
Author(s)
Stephen Wise, Etienne Cavalier, Pierre LUKAS, Stephanie Peeters, caroline Le Goff, Laura Briggs, Emma Williams, Ekaterina Mineva, Christine Pfeiffer, Hubert Vesper, Christian Popp, Christian Beckert, Jan Schultess, Kevin Wang, Carole Tourneur, Camille Pease, Dominik Osterritter, Ralf Fischer, Ben Saida, Chao Dou, Satoshi Kojima, Hope Weiler, Agnieszka Bielecki, Heather Pham, Alexandra Bennett, Shawn You, Amit Ghoshal, Chistian Vogl, James Freeman, Neil Parker, Samantha Pagliaro, Jennifer Cheek, Jie Li, Hisao Tsukamoto, Karen Galvin, Kevin Cashman, Hsuan-Chieh Liao, Andrew Norbert Hoofnagle, Jeffery Budd, Adam Kuszak, Ashley Boggs-Russell, Carolyn Burdette, Grace Hahm, Federica Nalin, Johanna Camara
Commutability is where the measurement response for a reference material (RM) is the same as for an individual patient sample with the same concentration of analyte measured using two or more measurement systems. Assessment of commutability is essential

Fault-tolerant quantum memory using low-depth random circuit codes

January 10, 2025
Author(s)
Jon Nelson, Gregory Bentsen, Steven Flammia, Michael Gullans
Low-depth random circuit codes possess many desirable properties for quantum error correction but have so far only been analyzed in the code capacity setting where it is assumed that encoding gates and syndrome measurements are noiseless. In this work, we

Uniform Laws and Regulations in the Areas of Legal Metrology and Fuel Quality

January 10, 2025
Author(s)
John McGuire, David Sefcik, Loren Minnich, Isabel Baucom, Katrice Lippa
This 2025 edition includes amendments made through the Committee on Laws and Regulations of the NCWM with technical guidance from the Office of Weights and Measures (OWM) of the NIST and input from weights and measures officials and industry

Small variant benchmark from a complete assembly of X and Y chromosomes

January 8, 2025
Author(s)
Justin Wagner, Nathanael Olson, Jennifer McDaniel, Lindsay Harris, Chunlin Xiao, Fritz Sedlazeck, Kishwar Shafin, Andrew Carroll, Justin Zook
The sex chromosomes contain complex, important genes impacting medical phenotypes, but differ from the autosomes in their ploidy and large repetitive regions. To enable technology developers along with research and clinical laboratories to evaluate variant

A Systems-Based Framework for Product Circularity Assessment

January 7, 2025
Author(s)
Gisele Bortolaz Guedes, Junwon Ko, Fazleena Badurdeen, I.S. Jawahir, Katherine Morris, Vincenzo Ferrero, Ardeshir Mashhadi, Ryan Bradley
One of the key aspects of Circular Economy (CE), particularly when focusing on the product level, lies in its emphasis on designing products to facilitate the circulation of resources and maximize value throughout their entire lifecycle. To effectively

WLAN Protocols Identification Using Machine Learning and Ensemble Models

January 7, 2025
Author(s)
Akimun Jannat Alvina, Yao Ma, Mark Golkowski
The growing demand for wireless communications has caused significant spectrum congestion, requiring multiple WLAN protocols to share limited spectrum resources. To address this, further research is necessary to optimize spectrum sharing and improve

Metadata Modeling for Manufacturing Enterprise Integration

January 6, 2025
Author(s)
Yan Lu, Boonserm Kulvatunyou, James Jim Wilson, Michael Figura, Josh Ki, David Noller
The continuous digitalization and digital transformation are expanding enterprise information exchange scenarios that span product data, process data sets, and supply chain documents. This paper samples common manufacturing enterprise metadata exchange

Materials Discovery in Combinatorial and High-throughput Synthesis and Processing: A New Frontier for SPM
